chore(deps): bump hyperpolymath/smtp-notify-action from 0.3.0 to 0.5.0

[dependabot]

Bumps hyperpolymath/smtp-notify-action from 0.3.0 to 0.5.0.

Release notes

Sourced from hyperpolymath/smtp-notify-action's releases.

v0.5.0

Newsgroup posting, on the same binary

protocol: nntp with newsgroups posts one article over implicit TLS (NNTPS, 563) or STARTTLS on the news port (RFC 4642, 119), authenticating with AUTHINFO USER/PASS. Transport selection is fail-closed and unchanged in shape from the SMTP path: a server that does not advertise the upgrade is refused before any credential is written.

Refusals name their own reason, including the two 4xx codes that are not retries — 440 at POST and 441 at the article, where a class-only rule would have advised a retry and duplicated the post. Malformed newsgroups and CR/LF in a header-bound value are refused before the socket is opened. The body is dot-stuffed on the wire and a Message-ID is generated per run.

The NNTP session is a second proven contract — spec/Nntp/ (6 rows implicit, 8 with STARTTLS, plus the Newsgroups grammar and newsgroupsNoInjection) — emitted into the same src/generated/smtp_fsm.zig, so the existing drift gate covers it. The SMTP section of that file is unchanged.

The Marketplace listing can finally be published

The publish form refuses a description of 125 characters or more (measured on the parsed value, so a folded scalar does not hide it) and reads action.yml from the release tag — which is why this ships as a tag rather than a commit on main. The description is now 110 characters with STARTTLS and 365 in it; the full text lives in the README, which the listing page renders. scripts/check-action.sh and the action-metadata job keep the limit from regressing, with a selftest proving 125 is refused and 124 accepted.

server_port now defaults to empty, meaning the port the protocol and transport imply: SMTP 465/587/25, NNTP 563/119.

Provenance

CI rebuilt both static musl binaries from this tag and verified they hash to exactly the SHA-256 pins inside this tag's action.yml before publishing. SHA256SUMS is attached:

2683da8f619dd5f310c9f6884da39e825c807c2c86a6319c19aba39b27f9c5c9  smtp-notify-x86_64-linux-musl

See CHANGELOG.adoc for the full entry, and KNOWN-DEFECTS.adoc for what is not proven — notably D-015: no real news server has ever seen this code; the end-to-end evidence is a containerised fixture.

v0.4.0

Static, byte-reproducible smtp-notify binaries. CI rebuilt them from this tag and verified they hash to exactly the SHA-256 pins inside this tag's action.yml before publishing.

Changelog

Sourced from hyperpolymath/smtp-notify-action's changelog.

== v0.5.0 — 2026-10-04

Newsgroup posting, and the release that can finally be listed on the GitHub Marketplace. The two are one release because the description fix can only take effect from a tag — the Marketplace validates action.yml at the release's tag, not on main — and a tag is what this release is for.

NOTE: The tag must be pushed immediately after this merge. Between the two, the tagged commit's action.yml names v0.5.0 assets that do not exist yet, and @main inherits that window; the release workflow refuses to publish unless the asset URL equals the tag, so the window is a property of the release process rather than of this tree. If the tag lands on a later day, correct this heading with a follow-up commit, as was done for v0.4.0.

=== Added

• protocol input (smtp | nntp, default smtp), chosen explicitly and never inferred. newsgroups set while protocol is smtp fails the step naming the mismatch, and protocol: nntp without newsgroups fails too, rather than either combination being guessed at.
• NNTP posting — one article per run. Implicit TLS (NNTPS, normally 563) or STARTTLS on the cleartext news port (RFC 4642, normally 119), with AUTHINFO USER/PASS (RFC 4643). The article carries From, Newsgroups, Subject (RFC 2047 for non-ASCII), Date, a generated Message-ID, optional Content-Language, MIME-Version, Content-Type and Content-Transfer-Encoding; the body is dot-stuffed on the wire. The STARTTLS path re-reads CAPABILITIES after the upgrade, as RFC 4642 §2.2 requires, and a server that does not advertise the upgrade is refused rather than posted to in the clear.
• A second proven contract. spec/Nntp/StateMachine.idr and spec/Nntp/Serialize.idr hold the NNTP session tables (6 rows implicit, 8 with STARTTLS) and the Newsgroups grammar, with the same style of properties as the SMTP spec: deterministic coverage, termination, ordering, and that the upgrade is on the walked path — plus newsgroupsNoInjection, the analogue of the Content-Language theorem. Both emit into the same src/generated/smtp_fsm.zig, so the existing drift gate covers them; the SMTP section of that file is unchanged.
• Failure attribution for the news session. A 201 greeting and a 440 reply are reported as "this server will not accept posts", 441 as the article itself being refused (both at POST and after the article, where a class-only rule would have advised a retry and duplicated the post), and a server advertising AUTHINFO SASL alone is refused before a credential is written. Malformed newsgroups, CR/LF in a header-bound input, an invalid Content-Language and empty credentials are refused before the socket is opened, so a typo does not read as a connection failure.
• scripts/nntp-sink.py and an e2e-nntp CI job. A one-shot NNTP server fixture, the news counterpart of the Mailpit container: the job posts an article and asserts the dialogue order, the canonicalised newsgroup list, the encoded-word subject, the generated Message-ID shape and the dot-stuffed line on the wire — then asserts that each refusal names its own reason and
